To all whom it may concern: 3

Be it known-that \ve, EDWARD J. DEEGAN and WiLLL-uu Honeson, citizens of the" United States of America,- residing at the city of N(\V'1 'O1l ,'l11 the county of Bronx and State of-Neiv York, have invented'c'er tain new and usefulImprovements in Regulators, of which the following is a specification.

Our invention relates to thermostatic regulators and particu'larly'to' a regulator of such character as to be adapted-to regulate the flow-of gas to radiators, heaters, or other devices, inthe use of which it is desired to reduce the fiOW of gas-When the heat of the surrounding air rises above a predetermined temperature.

Figure 1. is a plan or face vie'wof a regulator embodying our invention-J Fig. 2. is a sectional vie'ivof'said device.

Fig. 3. is a plan view of'the'same, representing the side of the baseopposite to that shown in Fig. 1.

Fig. 4. is a centrahvertical,sectional view through the regulator.

1 represents a base, preferably abrass casting, the part 2 being in the form of a flanged circular-disk'andthe part3, preferably integral with 2, in the form of a tube extending across said disk, preferably on a diametric line. I

This tube is provided With ports 4;, 5, usually screw threaded to permit convenient attachment to gas pipes or other forms of conduits.

The aperture from port 4 to port 5, is interrupted by a Wall 6, usually about midway between them, and through the side Walls of the respective sections of said tube which, as shown, are also parts of the disk 2, there are openings 7, on one side of the Wall 6,

and 8l2, on the other side of the Wall,

though We do not limit ourselves to a single opening or a plurality of openings on either side of said Wall. A minor aperture 13, through Wall 6, may be provided.

The outer faces of the Walls of these apertures are finished smoothly to constitute valve seats for the valve which is provided for closing them.

Seated on the disk 2 and fitting neatly within the circular flange at its edge there is a cover, 14, preferably a convex brass casting, and between said cover and the disk 2,

We seat a flexible diaphragm 15, its edge being secu'red'tightly to the cover and both'to the base 2.

A quantity of volatile fluid (Which may be ether) is placed in the in'closure formed by cover 14 and diaphragm '15 and hermetically sealed therein.

It will be noticed that this device presents V a considerable surface to tlie'action ofjthe surround ng anjfor instance thatof a room containing a gasradiator connected to the pipe to which the regulator is attached, and that as the tube an'd'the' base ispreferab'ly one piece, and the cover forn'is'one Wall of the inclosure' holding the volatile liquid, changes of temperature Wlll be quickly mas:

mittedtothat liquid. 7 p g The regulator forms a conduit from a section of tubing leading from the gas supply to another section leading to the radiator,

and all gas supplied to theradiator must pass through the regulator; Any change in the capacity of the passage will immediately change'the flow of gas through it to the radi ator.

Now thequantity been proportionedto the size'of the in closure and the space the" diaphragm must move to interrupt the flow of gas at a given temperature, say 70, the is'turned on and the radiator 1s lighted.

Asso'on as the teinpei-atui"e" of the room rises, that temperature Will be'transiiiitted, particularly through cover, Wall 14, to the volatile fluid and that'ivill begin to expand and 'to force the diaphragm 15, which constitutes a valve, toward the valve seats surrounding apertures 712, thereby reducing the flow of gas.

hen the temperature reaches the predetermined figuresay 70, the diaphragm valve Will rest upon the valve seats and shut off the flow of gas altogether, if it be arranged, as shown, toaccommodate that desire. If the aperture 13 be provided, a small quantity may pass through it to maintain a pilot flame at the radiator, or the parts and the volatile fluidmay be so proportioned that a temperature of 7 0 Will not absolutely close the normal conduit, but will merely reduce its capacity to such a degree as to merely furnish sufiicient gas to maintain said pilot flame. As soon as the temperature lowers, Whatever the cause, the fluid Will contract, the diaphragm recede and the passage may enlarge.

of volatile fluid having Ne prefer to make the apertures plural, as shown at 812 for the reason that such construction, aids in preventing the diaphragm from bulging so as to lose its resilient character and become useless, and also acts as a strainer, a series of small apertures being less likely to pass foreign matter than one large one.

W e also prefer to arrange the apertures orn the different sides of the Wall at even distances from the center of the diaphragm, when it is desired to seat it upon the surface surrounding all of the apertures, since an even seating is thus best secured. In short, that the valve seat, as a whole, shall be concentric, as it were, with the diaphragm outline, but we do not need to close passage 8-12 and also 7. If the diaphragm valve closes the passage or passages through the side wall on one side of the dividing wall, that answers the purpose, which, as noted, is the interference with the flow of gas to its place of use.

What we claim and desire to secure by Letters-Patent, is p 1. A regulator of the character designated for interposition in a gas supply conduit,

comprising a coupling section in the form of a pipe adapted for direct engagement with sections of said gas supply conduit, said coupling pipe section being formed with an internal perforate partition disposed transversely of the length and dividing it into a main pressure chamber and an attenuated pressure chamber, with lateral ports on either side of said partition opening into a diaphragm chamber, said diaphragm chamber, an elastic resilient imperforate diaphragm heremetically sealed therein and adapted to control the auxiliary flow of gas through said lateral ports to the attenuation chamber, and a volatile fluid inmesses terposed between said diaphragm and the outer wall of said diaphragm chamber, whereby a constant minimum gas supply to the attenuated pressure chamber is afforded by the perforate partition supplemented by an auxiliary supply thereto through the lat e 'al ports controlled by the diaphragm, for the purpose set forth.

2. A regulator of the character designated for interposition in a gas supply conduit, comprising a cylindrical coupling section in the form of a pipe adapted for direct engagement with sections of said gas supply conduit, said cylindrical coupling pipe section being formed with an internal perforate partition disposed transversely of the length of and dividing it into a main pressure chamber with lateral ports on either side.

of said perforate partition opening into a circular diaphragm chamber integral with the said cylindrical coupling pipe section and an attenuation chamber, said diaphragm chamber and a circular elastic resilient innperforate diaphragm hermetically sealed therein and adapted to act as a valve to control the auxiliary flow to gas through said lateral ports to the attenuation chamber, and a volatile fluid interposed between said diaphragm and the outer wall of said diaphragm chamber, whereby a constant minimum gas supply to the attenuated pressure chamber is afforded by the perforate partition supplemented by an auxiliary supply thereto through the lateral ports controlled by the diaphragm, for the purpose set forth.

In testimony whereof, we have signed our names to this specification this 17 day of April, 1916.
